USS Joseph P. Kennedy, Jr. is a World War II Gearing class destroyer. Although none of the Gearing class were built in time to see much combat, they represented the ultimate stage in World War II American destroyer design. Knowledge gained from the construction of the previous Fletcher and Allen M. Sumner classes was incorporated into the design of the Gearing destroyers, all of which remained in service after the war. Most of the Gearing destroyers were ultimately subjected to FRAM reconstruction and modernization, and many were converted into specialized antisubmarine warfare ships. USS Joseph P. Kennedy, Jr. took part in the first United Nations counteroffensive of the Korean War. Later, she gained worldwide attention during the Cuban Blockade when she intercepted a Soviet freighter. Stricken from the Navy Register in 1973, Kennedy is now berthed at Battleship Cove with the battleship Massachusetts, PT 617, PT 796, the Russion-built missile corvette Hiddensee, and the submarine USS Lionfish. Exhibits aboard USS Joseph P. Kennedy, Jr. include the Admiral Arleigh Burke National Destroyermen's Museum. USS Joseph P. Kennedy, Jr. is a National Historic Landmark.
